CIMAC WG08 | Future Fuel Scenarios and their impact on Lubrication

The purpose of this paper is to consider the various types of fuel, and combinations of fuels, that may be used by marine vessels through to 2025, and then to discuss the potential impacts that these fuel types may have upon engine lubrication. The paper also considers any mitigating factors that can assist in the safe and efficient use of such fuels.

The paper does not provide specific guidance on lubricant selection and use, but is intended to highlight potential problem areas, advise what symptoms to look out for, act as an ”awareness raiser” for future fuel use and give clues as to potential impacts on engine lubrication.

The guideline aims to understand the issue of cold corrosion which has been a regular occurrence with operators of large two-stroke marine engines due to engine operation at low loads. It intends .. more
